Thanks! This is quite helpful in gauging the need. I have some
resources that I can place in a project like this one, but I need to be
able to justify it - no insult meant... but I should have sent it only
to you rather than the list - there are probably no-one (in the list)
here that can gauge the need, as well as you. I did not ask for the
sizes in order to be dismissive, I asked so I can't justify it to the
best I can.
I do know DSP here in Berkeley very well and have interacted with them
in many occasions... but that does not help me know the numbers of
interested people.
It is shame that there are no Braille drivers for TeX. In the beginning
of the 90's when there was a driver for every printer/screen/computer
around the world, it seemed that one was going to pop up any day. It is
also a task that does not seem very complex, but people that understand
way more than I do would have to be consulted here.
TeX4ht may not be the best forum for this one, I don't think that
technically (even given Eitan's interest, more on that later) there is
much of a symbiosis going between tex4ht and a Braille DVI driver. At
the same time, there is quite a bit of work already done in the subject
and one can find litter all over the web:

TUG supports many specific project development and this is certainly one
that is well worth it. Some TUG directors read this mailing-list, but
this is better brought up with them directly.
On the specific issue of the ArXiV. Has anyone ever brought up this
issue with them ? They do have moneys and some of it strictly dedicated
to the issue of accessibility.

PS. The more I read about how Braille works, the more I get convinced
that the right way to do it would be to insert micro-pieces of
information on the DVI file that would guide the translation, and the
more I understand why Eitan was interested - this was his court!

Paulo,
I don't know how to estimate the number you asked for. There are
something like 50,000 blind and visually-impaired K-12 students in the
US and many many more in other countries, including much larger
numbers in China and India.
You might want to look at the archives of the international Blindmath
list to get a sense of the need.

However I should warn you that you could start a flame war if you were
to post your query to blindness organizations as it would be
considered as quite insulting.
You can also search on the term "math" in the profiles posted in
conjuction with the recent Braille21 international conference:

Note that this question is somewhat of a chicken and egg question.
While there are many braille readers around the world who would love
to have better access to advanced technical materials such as those on
arXiv, there are likely a much greater number of capable blind
students who've dropped out of math, science, and engineering courses
because they could not get accurate and timely braille transcriptions
of needed materials. (Here in the US it costs upward of $5000 to
transcribe a single technical book to braille.
http://www.atpc.net/index.php?Page=BFee&Action=SetToDefault )
Many college professors prepare course materials in LaTeX and many
braille-using students are reduced to reading LaTeX source rather than
braille math. I know that as a sighted person with a strong
background in math I find it very difficult to come to a good
mathematical understanding of math expressions in unrendered LaTeX so
I can only imagine how tedious it must be for a braille reader.
The fundamental point is not whether access to arXiv per se is needed
but that any solution to that problem would likely be a solution to
the more general problem of providing better access to technical
materials. You can read more about the general problem here.

P.S. Paulo if you are interested in helping with this problem I
suggest you start by contacting your UC Berkeley Disabled Students'
Program or find out what your own department is doing in this area.
